UTE STAT PATN FFTQ FERDINAND G. RUX, OF TIGERTON, WISCONSIN, ASSIGNOR OF ONE-HALF T0 GEORGE H. DREVRY, OF WALDO, WISCONSIN.

MAP-CASE.

To all whom it may concern:

Be it known that I, FERDINAND G. Box, a citizen of the United States, and resident of Tigerton. in the county of Shawano and State of Visconsin, have invented new and useful Improvements in Map-Cases, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention relates to improvements in map cases, and more particularly to that type which is adapted to be suspended from a support and to hold a number of maps.

It is one of the objects of this invention to provide a map case which is adapted to hold a plurality of maps and permit them to be independently withdrawn from the case and exposed to view, and to automatically remain in open or exposed position until released.

A further object of the invention is to provide a map case which is adapted to hold reversible maps and which may be swung around on its support to permit either side of the map being viewed. V

A further object of the invention is to provide a map case adapted to hold a number of maps and which may be revolved to turn the case in position to withdraw the particular map desired to be viewed.

A further object of the invention is to provide a map case provided with means for automatically holding the case in the position to which it has been swung or revolved.

With the above and other objects in view, the invention consists of the improved map case and its parts and combinations, as set forth in the claims, and all equivalents thereof.

In the accompanying drawing in which the same reference characters indicate the same parts in all of the views: Figure 1 is a side view of the improved map case, parts being broken away and other parts being shown in section; Fig. 2 is a transverse sectional view thereof taken on line 2-2 of Fig. 1, parts being broken away; Fig. 3 is a transverse sectional view thereof taken on line 33 of Fig. 1; and. Fig. 4 is a detail view of one of the map roller plugs.

Referring to the drawing the numeral 8 indicates a supporting wire which is adapted to extend across a school or other room and upon which a carriage bar 9 rides. The carriage is provided with pulleys 10 at its outer Specification of Letters Patent.

ends through which the wire loosely extends. A horizontally extending supporting bar 11 medially pivotally connected to the medial portion of the carriage by a pivot bolt 12 is provided at opposite ends with hearing brackets 13 through which extends the shaft 14 of the tubular case 15. To cause the supporting bar to snugly engage the carriage bar, a coiled spring 16 sur rounding the pivot bolt and interposed between the carriage bar and the nut 12' threaded on the upper end of the bolt, is provided which holds the bars in close engagement and also permits the supporting bar to be freely turned with relation to the carriage bar. The bolt opening of the upper portion of the carriage bar is counterbored to provide a recess 9 to accommodate the spring 16.

The case 15 comprises two heads 17 and 18 mounted fast on the shaft 14, and between which heads a sheet metal tubular map holder 19 is interposed. The ends of the map holder are inserted in circular grooves 20 formed in the heads to securely fasten the holder to the heads. The metal of the case is bent to form, in cross section, approximately an outer cylindrical shell 21 and a plurality of inner parallel tubular holders 22 having elongated slots 23 extending the entire length of the said tubes and through the cylindrical shell. The tubes are adapted to hold the maps 24 with the free ends of the maps extending through the slots so they may be easily withdrawn therefrom by pulling on the reinforcing strips 25 fastened to the outer ends of the maps. The reinforcing strips are are of larger diameter than the width of the tube slots and also serve to prevent the map ends from being drawn into the tubes. block 26 shaped to conform to the inner contour of the cylindrical casing and the tubular portions thereof serves to strengthen the parts. The head 17 is provided with openings 27 which register with open ends of the tubes to permit the maps to be inserted therethrough and into the tubes. The head 17 is further provided with slots 28 extending at an angle from the openings 27 t0 the periphery of the head, and these slots register with the slots of the tubes to permit the maps to be placed within the tubes with the free ends thereof extending through the slots. The maps are adapted to have their A medial reinforcing inner ends fastened to ordinary spring retrieved window shade rollers 29 of the auto matic type which are provided with dogs 30 to hold the roller in adjusted position. The pintle ends 31. of the rollers are journaled in the head 18 and the flattened spring holding keys of the opposite ends of the roller are adapted to be extended into the elongated recesses 33 of the tapered plugs 3%. These plugs fit snugly within the openings of the head 17 and are provided with looking pins or screws 35 projecting from their peripheries which enter the locking recesses 36 of the head 1.7. In order to securely and removably hold the plugs in the head a cap 37 is provided which is journaled on the shaft l t and bears against the outer face of the head and plugs. The cap is provided with an opening 38 extending to the periphery of the cap and the cap is adapted to be turned by means of the handle 39, to bring the opening into register with the plug it is desired to remove. The shaft lt is provided with handles or knobs 40 and 41 for convenience in turning the case and a coiled spring 42 surrounding the handle and interposed between the handle 40 and the depending bracket 13 adjacent thereto is adapted to frictionally hold the cylindrical casing in adjusted position.

In use double faced maps are preferably fastened to the rollers and wound thereon and the rollers are then inserted in the map tubes and the plugs are placed within the head openings and in engaging position with the flattened spring holding keys. The entire device may now be slid on the supporting wire to the desired place in the room and the case revolved until the map tube holding the map wanted is in the lowermost position. The map is now pulled down and out of the map tube to expose the map to view and the map will be held in this position by the locking dogs until released by a slight downward pull. when the spring of the roller will automatically draw the map into the tube. If it is desired to view the opposite side of the map the supporting bar is swung around on the carriage bar until the other side is in front.

From the foregoing description it will be seen that the map case is adapted to hold a plurality of maps which may be easily, independently viewed when desired.
